The reproducibility of three questions, related to fullness, satiety and desire to eat, rated on an unmarked triangle was verified. In four sessions 12 volunteers ate pasta with tomato sauce (520 kcal) and were asked to rate the sensations felt. There was no difference in rating scores of the replications so the proposed questionnaire provides a stable measure of sensations related to satiety. Subsequently three satiety conditions were studied. Two foods, one rich in carbohydrate, pasta (baked macaroni) and the other in protein, polpette (meatballs), were used as loads at two calorie levels and as preload before an "ad libitum" meal. All the three questions proved useful in discriminating between the different satiety conditions. The food intake underlines the specificity of satiety: subjects, after eating a preload which previously had satiated them, ate other foods in different amounts depending on the kind of preload eaten. Food intake was significantly higher after the pasta preload, furthermore "fullness" and "satiety" ratings were significantly highest after the meatball preload, suggesting that in our experimental conditions, meatballs were more satiating than pasta. In conclusion, this study highlights the validity of using several quite different questions to study hunger and satiety, together with the actual food intake.
对在一个无标记三角形上评定的与饱腹感、饱足感和进食欲望相关的三个问题的可重复性进行了验证。在四个实验环节中，12名志愿者食用了番茄酱意大利面（520千卡），并被要求对所感受到的感觉进行评分。各次重复的评分分数没有差异，因此所提出的问卷为与饱腹感相关的感觉提供了一种稳定的测量方法。随后研究了三种饱腹感状态。两种食物，一种富含碳水化合物，即意大利面（烤通心粉），另一种富含蛋白质，即肉丸子，在两种热量水平下用作负荷，并在“随意”进餐前用作预负荷。所有这三个问题在区分不同的饱腹感状态方面都被证明是有用的。食物摄入量突出了饱腹感的特异性：受试者在食用了先前使其产生饱腹感的预负荷后，根据所食用预负荷的种类，会摄入不同量的其他食物。食用意大利面预负荷后的食物摄入量显著更高，此外，食用肉丸预负荷后的“饱腹感”和“饱足感”评分显著最高，这表明在我们的实验条件下，肉丸比意大利面更具饱腹感。总之，本研究强调了使用几个截然不同的问题来研究饥饿和饱腹感以及实际食物摄入量的有效性。
